Exchange to exchange (sometimes Exchange-to-exchange, abbreviated E2E) is integration, between certain pairs of computer systems. To qualify as E2E, each of the paired systems must have a primary use of acting as an exchange, or gateway, among its own customers.
A common example is a connection between stock brokerage firms' internal systems and systems of a stock market in which the broker trades.[1] These connections are often facilitated by middleware services, such as object request brokers.
Each E2E partner system has a primary function to its own clients of allowing them to transfer information or conduct other transactions, This is a form of the business to business (B2B) commerce model, as each E2E partner is a B2B gateway for its clients, and in turn exchanges information with at least one other B2B gateway.[2] The connection between the two B2B systems (exchanges) is then an exchange to exchange integration.
E2E is an alternative to direct application to application integration (A2A),[3] though some A2A can be classified as E2E.
